Note: This trick requires two Game Boy Advance Wireless Adapters and another Game Boy Advance with Boktai 2. When the game is powered on, attach the Wireless Adapter before the title screen appears. A "Crossover Battle Mode" option will now appear below the "Continue" option at the starting menu. You can play against the Boktai 2 player to see who can defeat Shade Man faster.

Defeating Blizzard Man

With Snowball 1, he will roll out a pair of snowballs at you. With Snowball 2, Blizzard Man himself will become a snowball and roll at you. He will strike the back row and cause a pair of snow drifts to build up on two random panels on your side. With those are there, you will lose access to the panels. They will, however, eventually melt. With Frost Breath, He will jump to the front column on his side and try breathing ice on you. You have two columns and he has four. If you do not kill him within one phase, he will heal and drop a pair of snowballs on you, doing 40 damage per Navi. Blizzy does not really do much, so attack as desired. After the fight is over, Blizzard Man blows up and the whole area is cleared of Dark Panels. The first Liberate Mission has been a success. You will get a Blizzard Man B chip from Proto Man when you defeat Blizzard Man.
